Not fit for pupose. I try this for about 2weeks and during that time my ability to walk was greatly reduce and the pain I was in was unbearable. I had a rest from it until I was in less pain and could walk a little more. On the second try of it I only managed a week. I phoned to find out how to return it and get a refund (I was not worried about the extra insurance I had taken out on it) I was informed that lots of people have found it useful and I could not return it and get a refund. I told the girl I was speaking t it was not fit for the purpose it had be sold to be and basically was tod tough try and sale it privately. So I would say stay away from this as it does not work it makes matters worse and the customer service is rude and unhelpful. The chances of get you money back is nil.

Not a useful product. The Kyrobak did nothing to alleviate my low back pain, so I have returned it pursuant to their 60-day money back guarantee. I do not recommend Kyrobak.

Kyrobak If I could give this item a zero, I would. I really thought this was going to be an authentic device that would give me some relief and back pain. After only six uses, the interior mechanism, gears, whatever it is that makes it work, started stuttering and grinding. I only weigh 145 pounds so I know it’s not because of my weight. When I contacted the company to get a refund from Brand Street Market (brandstreetmarket.com)they refused without me paying for return shipping which is $37. Now, I can understand paying for return shipping if I didn’t like the item. However, this item broke after only one week and they expect me to cover return shipping. I am so tired of fraudulent companies taking advantage of people and our hard earned money. Do not buy this item it’s a piece of plastic crap. Do not buy from this company they are thieves and know they are selling crap.

notice of improvement I do feel there has been a noticeable improvement in reducing my back pain. It isn't completely gone like I had hoped but I am certainly more comfortable than before staring to use it. I am hoping I will continue to see improvement by daily use either once or twice a day.

Hard Lesson Learned Anyone who has even mild back issues should NOT use Kyrobak. I have experienced a "shift in my spine" after using daily for two months. I really wanted it to help, but has landed me in worse shape. Dr. said I should never try something that has not been studied. Hard Lesson Learned!
